Simple Machines X-Forwarded-For HTML Injection Vulnerability

Simple Machines X-Forwarded-For HTML Injection Vulnerability

Simple Machines is prone to an HTML-injection vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.

Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing for the theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.

This issue is reported to affect Simple Machines version 1.0.6 and earlier.
